LATCH-type (ISOFIX) child seat secur-
ing system
GWARNING
For LATCH-type (ISOFIX) child restraint sys-
tems in which the child is secured using the
safety belt integrated in the child restraint
system, the maximum permissible weight of
the child and child restraint system together
is 73 lbs (33 kg).
If the child and the child restraint system
together weigh more than 73 lbs (33 kg), the
LATCH-type (ISOFIX) child restraint system
with integrated safety belt no longer offers
sufficient protection. The LATCH-type (ISO-
FIX) child seat securing system may be over-
loaded, and the child may not be restrained in
an accident, for example. This poses an
increased risk of injury or even fatal injury.
If the child and the child restraint system
together weigh more than 73 lbs (33 kg),use
only a LATCH-type (ISOFIX) ch ildrestraint sys-
tem in whic h the ch ild isalso secured with the
veh icle seat belt. Also secure the ch ild
restraint system with the Top Tether belt,if
available.
Regularly check that the permis siblegross
weight of the ch ildtogether with the ch ild
restraint system isstill maintained.
Alwa ys co mply wit h the manufacturer's instal-
lation and operating instructions for the ch ild
restraint system used.
Before installing a ch ildseat, move the rear seat
backrest to an upright position. Do not adjust
the backrest of a seatw
it h a LATCH-type (ISO-
FIX) ch ildrestraint system installed.
Before every tr ip,make sure that the LATCH-
type (ISOFIX) ch ildrestraint system isengaged
correct ly inboth LATCH-type (ISOFIX) securing
rings
!When fitting the ch ildrestraint system in
veh icleswit h a rear bench seat, make sure
that the seat beltfor the center seat does not
get tr apped. Otherwise, the seat beltcould be
damaged.

ISOFIX isa standardized securing system for
specially designed child restraint systems on
certain rear seats. LATCH-type (ISOFIX) secur-
ing rings :for a LATCH-type (ISOFIX) child
restraint system are installed between the seat
cushion and the seat backrest.
Non-LATCH-type (ISOFIX) child seats may also
be used and can beinstalled using the vehicle's
seat belt system. Install the child seat according to the manufacturer's instructions.
Top Tether
Introduction
Top Tether pro vides an additional connection
between the child restraint system secured with
a LATCH-type (ISOFIX) system and the vehicle.
This helps reduce the risk of injury even further.
If the child restraint system isequipped with a
Top Tether belt, this should always be used.

Child restraint system on the front-
passenger seat
General notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
the child restraint system on a rear seat.
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
always observe the instructions and safety
notes on the "Occupant Classification System
(OCS)" (
Ypage 52).
You can thus avoid the risks that could arise as a result of:
Ran incorrectly categorized person in the front-
passenger seat
Rthe unintentional deactivation of the front-
passenger front air bag
Rthe unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board
Rearward-facing child restraint system
If it is absolutely necessary to install a rearward-
facing child restraint system on the front-
passenger seat, always make sure that the
front-passenger front air bag is deactivated.
Only if the PASSENGER AIR BAG OFF indicator
lamp is permanently lit (
Ypage 46 )is the front-
passenger front air bag deactivated.
Always observe the child restraint system man-
ufacturer's installation and operating instruc-
tions.
Forward-facing child restraint system
If it is absolutely necessary to install a forward-
facing child restraint system on the front-
passenger seat, always move the front-
passenger seat as far back as possible. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the child
restraint system must lie as flat as possible
against the backrest of the front-passenger
seat. The child restraint system must not touch
the roof or be subjected to a load by the head
restraint. Adjust the angle of the seat backrest
and the head restraint position accordingly.
Always make sure that the shoulder belt strap is

correctly routed from the vehicle belt outlet to
the shoulder belt guide on the child restraint
system. The shoulder belt strap must be routed
forward and down from the vehicle belt outlet. If
necessary, adjust the vehicle belt outlet and the
front-passenger seat accordingly.
Always observe the child restraint system man-
ufacturer's installation and operating instruc-
tions.

GWARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Pro- tect it with a blanket, for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in
the vehicle.

Important safety notes
GWARNING
Children could become trapped if they adjust
the seats, particularly when unattended.
There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
You could lose control of your vehicle if you do the following while driving:
Radjust the driver's seat, head restraint,

ing wheel and mirror and fasten your seat belt before starting the engine.
GWARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat.
GWARNING
If the driver's seat is not engaged, it could
move unexpectedly while the vehicle is in
motion. This could cause you to lose control of the vehicle. There is a risk of an accident.
Always make sure that the driver's seat is
engaged before starting the vehicle.
GWARNING
The front-air bags for could also injure the
vehicle occupants in the front If the front
seats are positioned too close to the dash-
board or steering wheel. This poses an
increased risk of injury or even fatal injury.
Always adjust the front seats so that they are
as far from the front air bags as possible. Also
observe the notes on the correct adjustment
of the seats.
GWARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
GWARNING
If the head restraints are not installed or not
adjusted correctly, they cannot provide pro-
tection as intended. There is an increased risk
of injury in the head and neck area, e.g. in the event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.

!To avoid damage to the seats and the seat
heating, observe the following information:
Rkeep liquids from spilling on the seats. If
liquid is spilled on the seats, dry them as
soon as possible.
Rif the seat covers are damp or wet, do not
switch on the seat heating. The seat heat-
ing should also not be used to dry the seats.
Rclean the seat covers as recommended;
see the "Interior care" section.
Rdo not transport heavy loads on the seats.
Do not place sharp objects on the seat
cushions, e.g. knives, nails or tools. The
seats should only be occupied by passen-
gers, if possible.
Rwhen the seat heating is in operation, do
not cover the seats with insulating materi-
als, e.g. blankets, coats, bags, seat covers,
child seats or booster seats.
Your seat must be adjusted in such a way that
you can wear the seat belt correctly.
Observe the following points:
RPosition the backrest in an almost vertical
position so that you are sitting virtually
upright. Do not drive with the backrest
reclined too far back.
RYour arms should be slightly bent when you
are holding the steering wheel.
RAvoid seat positions that prevent the seat belt
from being correctly routed. The shoulder
section of the belt must be routed over the
middle of your shoulder and be pulled tight
against your upper body. The lap belt must
always pass across your lap as low down as
possible, i.e. over your hip joints.
RAdjust the head restraint so that it supports
the back of the head at eye level.
RThe distance from the pedals should be such
that you can depress them fully.
